Question

find each edge of cubical Box if it's total surface area is 24m2

Answer 1

Here is your answer.

T.S.A = 6a^2
24 = 6×a^2
a^2=24/6
a^2= 4
a = 2 m.

Edge of cube = 2m

Hope that this helps you.

Answer 2

Total Surface Area of a cube = 6a

According to question

T.S.A = 24

6a² = 24

a² = 4

a = √4

a = 2 m
